focusing on a single div amidst a sea of interwoven dynamically generated divs

I am currently working with the liferay framework and I am facing a challenge where I need to apply inline JavaScript to target a very specific div on my webpage. The catch is that this div is nested within multiple dynamically added divs with varying classes and IDs. To make matters more complicated, these divs can either be siblings or nested within each other randomly.

Here's an example of what I'm dealing with:

<div class="known-class">
<div class="unknown dynamicallygenerated"></div>
<div class="unknown dynamicallygenerated">
    <div class="unknown dynamicallygenerated">
        <div class="unknown dynamicallygenerated"></div>
        <div class="unknown dynamicallygenerated">
            <div class="DIV-I-WANT-TO-TARGET">this is the div i need to Target with my css/javascript</div>
        </div>
    </div>
</div>

Simply targeting it using the class name won't work due to similar classes elsewhere in the page. A possible solution would be something like:

jQuery('.known-class .DIV-I-WANT-TO-TARGET')

However, this approach fails because my desired div is not directly under the ".known-class" div, but nested inside others.

I have been exploring if there might be a jQuery method to assist me. Perhaps:

Select any div with .DIV-I-WANT-TO-TARGET class that is nested within another div containing .known-class

Is there a way to achieve this? Your help is greatly appreciated!

Answer №1

Here is an example of how you can achieve this:

// To target the known-class and locate all children with DIV-I-WANT-TO-TARGET
$('div.known-class').find('div.DIV-I-WANT-TO-TARGET');

// To target the known-class and find the first occurrence of DIV-I-WANT-TO-TARGET
$('div.known-class').find('div.DIV-I-WANT-TO-TARGET').first();
$('div.known-class').find('div.DIV-I-WANT-TO-TARGET:first');
$('div.known-class').find('div.DIV-I-WANT-TO-TARGET:eq(0)');
$('div.known-class').find('div.DIV-I-WANT-TO-TARGET').eq(0);

To target the desired div in your stylesheet, you can use the following code:

 .known-class div div div div{}

The last div within the mentioned selector is the one that you want to target.

If you are organizing the divs from outer to inner, follow these steps:

Give each div a unique name followed by a number starting from 1.

<div class="known-class">
  <div class="unknown dynamicallygenerated" id="dynamicdiv1"></div>
    <div class="unknown dynamicallygenerated" id="dynamicdiv2">
       <div class="unknown dynamicallygenerated" id="dynamicdiv3">
           <div class="unknown dynamicallygenerated" id="dynamicdiv4"></div>
              <div class="unknown dynamicallygenerated" id="dynamicdiv5">
                <div class="DIV-I-WANT-TO-TARGET" id="dynamicdiv6"></div>
        </div>
    </div>
</div>

Use jQuery [.each][1] to iterate through all the divs in the document.

$( document.body ).click(function() {
  $( "div" ).each(function( i ) {
    if ( this.style.color !== "blue" ) {
      this.style.color = "blue";
    } else {
      this.style.color = "";
    }
  });
});

Once you reach the last item in numerical order, apply attributes to that div using any split function.

Make sure to choose the final div within a specified class:

$('.specified-class').find('div:last').css('background', 'Blue')

OR if you prefer to target all elements with the specified class:

$('.specified-class').each(function() {$(this).find('div:last').css('background', 'Blue')});

It's important to note that your selector is functioning correctly:

$('.known-class .DIV-I-WANT-TO-TARGET')

By including a space, the selector will locate any descendant.

If you use the > operator, the search is restricted to direct descendants (immediate children) only.

Therefore,

$('.known-class > .DIV-I-WANT-TO-TARGET')

would not yield the desired result.
